LED LIGHT AND LIGHT-EMITTING DECORATION ASSEMBLY

CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to Chinese Application No. 202120298824.7, filed February 2, 2021, the entire content of which is incorporated herein by reference.

TECHNICAL FIELD

The present disclosure generally relates to the light-emitting diode (LED) lighting device technology field and, more particularly, to an LED light and a lighting decoration assembly.

BACKGROUND

A light-emitting diode (LED) light has advantages such as high efficiency, energy-saving, long lifetime, healthy light, environment protection, etc. Thus, the LED light has become a most widely used light-emitting lighting device in daily life.

Many types of LED lights exist, for example, a G9 bulb, which is widely used as a decoration light. The G9 bulb may refer to a light having a head with two or more protrusion contacts, and the distance between two pins of the head is 9mm. Such a bulb usually has a matte or colored gloss, which can reduce damages to human eyes. The G9 bulb is mainly configured for accent lighting and desktop lighting, and as an indoor or outdoor chandelier and a lamp arranged under a cabinet and a drawer. If such a bulb has a glass housing, an encapsulation process is required during the production process. That is, inert gas is introduced into the bulbs. After the glass becomes soft at a high temperature, the bulb is sealed. That is, the bulb is encapsulated. In this process, a high temperature above 500℃ is required for softening the glass.

Currently, an LED light usually has an electrolytic capacitor, such as an electrolytic capacitor configured to reduce rippling and flickering. A glass position of encapsulated bulb has a certain distance from the electrolytic capacitor during the production process. Since the installation space inside the bulb is small, the size is limited. The temperature resistance of the electrolytic capacitor generally does not exceed 105℃. Thus, the production process may easily cause damage to the electrolytic capacitor.

DETAILED DESCRIPTION

In order to make the purpose, technical solutions, and advantages of embodiments of the present disclosure clearer, the technical solutions of embodiments of the present disclosure are described in detail in connection with the accompanying drawings of embodiments of the present disclosure. Apparently, described embodiments are some embodiments of the present disclosure, but not all embodiments. Based on embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts should be within the scope of the present disclosure.

Light-emitting diode (LED) lights are widely used due to advantages of high efficiency and energy saving. To de-ripple and de-flash, an electrolytic capacitor may be arranged in a current LED light structure. A G9 bulb (the G9 bulb refers to a bulb having a head with two or more protrusion contacts, where a distance between two pins of the bulb is 9mm) may be taken as an example. The G9 bulb made of glass may be sealed in the production process through an encapsulation process. That is, the bulb is encapsulated. In this process, the glass may need to be softened through heating at a high temperature. The heating temperature may generally be above 500℃. For the G9 bulb, an internal space of the bulb may be small, and the glass position of the encapsulated bulb may be close to the electrolytic capacitor. Thus, the high temperature may cause damage to the electrolytic capacitor. In fact, smaller bulbs may have similar problems. For example, a G4 bulb (the G4 bulb refers to a bulb having a head with two or more protrusion contacts, where a distance between the two pins of the head is 4 mm) may also have the same problem.

For the above-mentioned problems, the present disclosure provides an LED light 1. Specific embodiments are described to explain how the technical solutions of the present disclosure solve the above-mentioned technical problems. Following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present disclosure are described below in connection with the accompanying drawings.

FIG. 1 is a schematic front view of the LED light 1 according to some embodiments of the disclosure. FIG. 2 is a schematic exploded view of the LED light 1 according to some embodiments of the disclosure. FIG. 3 is a schematic left view cross-section diagram of the LED light 1 according to some embodiments of the disclosure.

As shown in FIGS. 1 and 2, the present disclosure provides the LED light 1. The LED light 1 includes a glass housing 11, an LED light-emitting assembly 12, a heat insulation protection member 13, and an electrical connector 14. The LED light-emitting assembly 12 includes an LED light-emitting module 122 and a capacitor module 124. The capacitor module 124 is arranged between the electrical connector 14 and the LED light-emitting module 122. The electrical connector 14 and the capacitor module 124 are electrically connected to the LED light-emitting module 122. Both the capacitor module 124 and the LED light-emitting module 122 are located in the glass housing 11. The heat insulation protection member 13 is arranged outside of the capacitor module 124 and between the capacitor module and the glass housing to isolate the capacitor module 124 from the glass housing 11.

The above-mentioned electrolytic capacitor may include, for example, an electrolytic capacitor configured to de-ripple and de-flickering. The heat insulation protection member 13 is arranged outside of the capacitor module 124 and between the capacitor module 124 and the glass housing 11 to isolate the capacitor module 124 from the glass housing 11. Thus, heat insulation may be effected during production process.

The LED light of the present disclosure includes the G9 or the G4 bulb, etc. Whenever a bulb has a small internal space and/or the internal components of the bulb are likely to be damaged due to high temperature during the encapsulation process, the concept of the present disclosure may be used.

The above-mentioned LED lamp 1 provided by the present disclosure can protect the electrolytic capacitor of the LED lamp 1 from being damaged due to the high temperature during production.

Refer to FIGS. 1 and 2, in some embodiments of the present disclosure, the above-mentioned heat insulation protection member 13 covers a periphery of the capacitor module 124, that is, surrounding a sidewall of the capacitor module 124 in a circle. By separating the capacitor module 124 from the glass housing 11 through the peripheral side, the capacitor module 124 may be protected from the high temperature at a greatest degree.

In some embodiments, the heat insulation protection member 13 may be in a cylindrical member with an opening at an end. The capacitor module 124 may be accommodated in the heat insulation protection member 13 through the opening of the heat insulation protection member 13. That is, the capacitor module 124 may be inserted into the heat insulation protection member 13 from the opening. Thus, an internal diameter of the opening of the heat insulation protection member 13 may be greater than an outer diameter of the capacitor module 124.

In order to make the heat insulation protection member 13 have a better heat insulation effect, a seal cover may also be arranged at the opening of the heat insulation protection member 13. A wire insertion hole may be arranged at the seal cover. The capacitor module 124 may be arranged in the heat insulation protection member 13 through the opening. The seal cover may be covered at the opening. The connection wire between the heat insulation capacitor module 124 and the LED light-emitting module 122 may pass through the wire insertion hole of the seal cover. By arranging the seal cover, the heat insulation protection member 13 may better insulate the capacitor module 124 and keep the capacitor module 124 from being damaged due to the high temperature during production.

The material of the above-mentioned protection member may include a material with high-temperature resistance and poor thermal conductivity, for example, a ceramic member, a temperature-resistant rubber member, a temperature-resistant plastic member, or an asbestos member. The heat insulation protection member 13 made of these materials may have a better temperature resistance effect.

In some embodiments, the LED light 1 of the present disclosure may further include a support member. The support member may be fixed between the glass housing 11 and the heat insulation protection member 13 and configured to support the heat insulation protection member 13. With the support member, a relative position of the heat insulation protection member 13 and the capacitor module 124 may be fixed, which avoids the heat insulation protection member 13 from falling off.

In some other embodiments, as shown in FIG. 1, the electrical connector 14 includes a pin 146 and a rigid connection wire 142. An end of the connection wire 142 is connected to the pin 146, and another end of the connection wire 142 is connected to the LED light-emitting module 122. The connection wire 142 has a curved section 142a. That is, the connection wire 142 is bent along a radial direction of the heat insulation protection member 13. The heat insulation protection member 13 is arranged at the curved section 142a.

As shown in FIGS. 1 and 2, the pin 146 is a light pin and is configured to be connected to an external power supply. The electrical connector 14 further includes a connection plate 144. The connection plate 144 may include a metal sheet with good conductivity and is arranged between the connection wire 142 and the pin 146 and configured to connect the pin 146 and the connection wire 142. A shape of the connection plate is not limited. For example, the connection plate may be rectangular.

In some embodiments, the curved section 142a may be bent from the axial direction of the heat insulation protection member 13 to the radial direction of the heat insulation protection member 13 to form a support step.

In some embodiments, the rigid connection wire 142 may be bent into a shape that can support the heat insulation protection member 13. The connection wire 142 may be bent along the radial direction of the heat insulation protection member 13 into a horizontal step. The step can support the heat insulation protection member 13. By using the connection wire 142 to support the heat insulation protection member 13, no additional support structure may be needed, which saves process steps, and the structure of the LED light 1 is simpler.

In some other embodiments, referring to FIG. 1, two connection wires 142 are arranged. Curved sections 142a of the two connection wires 142 are bent in opposite directions. That is, both curved sections 142a are bent radially toward the heat insulation protection member 13 and jointly support the heat insulation protection member 13.

As shown in FIG. 1, in some embodiments, the two connection wires 142 are arranged on both sides of the heat insulation protection member 1 symmetrically along the radial direction. The curved sections 142a of the two connection wires 142 are bent from the axial direction of the heat insulation protection member 13 to the radial direction of the insulation protection member 13. As such, the connection wires 142 may better support the heat insulation protection member 13 to maintain the balance of the capacitor module 124.

In some other embodiments, a number of connection wires 142 may not be limited to two. More connection wires 142 may be arranged as needed. Then, some or all of the connection wires 142 may be selected to arrange the curved sections 142a to support the heat insulation protection member 13. The connection wires symmetrical along the radial direction of the heat insulation protection member 13 may be selected to be bent into a support platform to jointly support the heat insulation protection member 13, which is beneficial to the balance of the heat insulation protection member 13.
